  • Initial data from the combination of imdusiran and VTP-300 show meaningful reductions of HBsAg levels that were maintained well below baseline.
  • In HBV003, 31% of participants with screening HBsAg level of ≤200 IU/mL had >1 log HBsAg reductions.
  • VTP-300 was generally well-tolerated in both trials.
Barinthus Biotherapeutics plc (NASDAQ: BRNS), formerly Vaccitech plc, today announced the presentation of data from two HBV clinical trials at The American Association for the Study of Liver Diseases (AASLD) – The Liver Meeting® 2023. The presentations include an oral presentation of data from HBV003, an ongoing Phase 2b trial designed to further evaluate the safety and efficacy of VTP-300 when combined with a low-dose anti-PD-1 antibody, and standard-of-care (SoC) nucleos(t)ide analogue (NUC) therapy. Alongside this, a late-breaking poster presentation with interim data from patients with chronic hepatitis B (CHB) from the Phase 2a AB-729-202 trial combining Arbutus Biopharma Corporation’s (NASDAQ: ABUS) RNAi therapeutic candidate, imdusiran (AB-729), with Barinthus Bio’s T cell stimulating immunotherapeutic candidate, VTP-300, and SoC NUC therapy.
